White Blood Cells

White blood cells, also called leukocytes, are an important part of the body's immune system. These cells help the body fight off infections and foreign invaders. There are several types of white blood cells, each with its own function in protecting the body.

Types of White Blood Cells

There are five main types of white blood cells:

1. Neutrophils: These are the most common type of white blood cell and are essential for fighting bacterial infections.
2. Lymphocytes: These cells are crucial for the body's adaptive immune response, producing antibodies and destroying infected or abnormal cells.
3. Monocytes: Monocytes help to break down bacteria and other harmful substances in the blood.
4. Eosinophils: These cells are involved in fighting off parasitic infections and play a role in allergic reactions.
5. Basophils: Basophils release histamine and other chemicals involved in inflammation and allergic responses.

Functions of White Blood Cells

White blood cells have several important functions:

• Defending the body against pathogens such as bacteria, viruses, and fungi
• Producing antibodies to target specific pathogens
• Removing dead or damaged cells and tissues
• Assisting in the body's inflammatory response
